5. Combustion of liquid fuels 5.1 Atomization of fuel Liquid fuels such as gasoline‚ diesel‚ fuel oil light‚ fuel oil heavy or kerosene have to be atomized and well mixed with the combustion air before burned. Therefor nozzles are used. Nozzles are divided into two groups: Pressure atomizers and twin-fluid atomizers. 5.1.1 Pressure atomizers Pressure atomizers are differed into turbulence nozzles and liquid sheet nozzles. At both types of nozzles the energy from the liquid pressure is converted

Efficient Propeller Design | AbstractHow does a helicopter generate enough lift to fly? How does a speedboat get moving fast enough to pull someone on water skis? Here ’s a project on designing propellers to do the job. ObjectiveThe goal of this project is to investigate how changes in chord length affect the efficiency of propellers.IntroductionA propeller‚ like an airplane wing‚ is an airfoil: a curved surface that can generate lift when air moves over it. When air moves over the surface of

achieved through the generation of large amounts of aerodynamic downforce. Formula One cars race at speeds of up to 350 km/h (220 mph) with engines limited in performance to a maximum of 18‚000 revolutions per minute (RPM). The cars are capable of lateral acceleration in excess of 5 g in corners. The performance of the cars is very dependent on electronics – although traction control and other driving aids have been banned since 2008 – and on aerodynamics‚ suspension and tyres. The formula has had much

CHAPTER 1 INTRODUCTION: Bernoulli’s Principle is a physical phenomenon that was named after the Swiss scientist Daniel Bernoulli who lived during the eighteenth century. Bernoulli studied the relationship of the speed of a fluid and pressure. The Swiss mathematician and physicist Daniel Bernoulli (1700-1782) discovered the principle that bears his name while conducting experiments concerning an even more fundamental concept: the conservation of energy. This is a law of physics that holds that

Observations from prototypes: (Prototype rockets are much smaller and use 500ml pop bottles) I tried to make my prototype rocket have a pointy nose‚ just because it can be aerodynamic‚ pointy nose rockets fly great‚ it’s just after the rocket has crashed nose down‚ it will fail to protect the egg because

been lost in our car: some of the air in the balloon may have escaped through the gaps between the balloon and the straws‚ this might have slowed down the car by a fraction. The friction from the wheels may have resulted in loss of energy. The aerodynamics of the car could have altered the speed‚ but in this experiment I don’t think this would have mattered that much judging by the speed and the scale of the car. I think the most amount of energy would have been lost in the wheel alignment this is

Types of aerial locomotion Animal aerial locomotion can be divided into two categories - powered and unpowered. In unpowered modes of locomotion‚ the animal uses on aerodynamics forces exerted on the body due to wind or falling through the air. In powered flight‚ the animal uses muscular power to generate aerodynamic forces. Animals using unpowered aerial locomotion cannot maintain altitude and speed due to unopposed drag‚ while animals using powered flight can maintain steady‚ level flight as

things to win. In order to win‚ teams have to understand the science of racing. The science of racing includes things like track surface‚ tire wear‚ aerodynamics‚ fuel consumption‚ and track line. The drivers usually changes their tires every 50 to 80 laps‚ unless if there is a caution flag. This depends on the track surface and tire type. Aerodynamics is also important because it controls your speed and how much grip the car has in the turns. Fuel usage is important to not lose the race by running
